Neutron Scattering Reduction

This project provides tools for data reduction for neutron and xray scattering.

reflred

A python package for loading, modifying and saving reflectivity data sets.

ospecred

A python package for loading, modifying and saving off-specular reflectivity data sets.

sansred

A python package for loading, modifying and saving small-angle neutron scattering (SANS) data sets.

web_gui

RPC access to reduction libraries, with javascript frontend (stateless)

To load data from a local store in web reduction, go to menu->data->add source->local (must be running the server locally, with the local datastore enabled in config)

Installation and use

Method 1: pypi install

pip install reductus

Then start the server with:

reductus

Method 2: Docker Compose

This is the easiest way to get started. Clone the repo, the change directories into the repository and run:

docker-compose build
docker-compose up -d

This will result in a trio of docker containers being spun up, one with a web server for the interface ('web_gui'), one with the backend calculation RPC server ('reductus') and one with the Redis cache.

Files in ./web_gui/testdata/ will be mapped into the server at /data, for testing the local file handling. Changes to the python code can be incorporated into the containers by stopping them, then repeating the build and up commands above.

To stop:

docker-compose stop

To access the client, if using the new Docker beta navigate to http://localhost:8000/web_gui/web_reduction_filebrowser.html On Windows 7, if using docker-machine, you will have to get the IP of the default docker install and use that instead of localhost, e.g. :

docker-machine ip default

In my case it was http://192.168.99.100:8000/web_gui/web_reduction_filebrowser.html

Method 3: Clone github repo and build, run directly in console

Clone the repo, then install (might be a good idea to make a virtualenv first), e.g.

python setup.py install

Then start the server with:

cd web_gui
python server_flask.py 8002

and visit the page http://localhost:8002/static/index.html
